Application ined my zo; i923.' serial no. 652,763.

To all whom z't may concern:

Be it known that I, CESARE BARBIERI, a

subject of the King of Italy, and a resident vented certain new and'useful Im rove` of the city of New York in the county of New York andState of Nzew York, have inments in a Machine for Forming and luingPaper Cups; and I do hereby declare that l the following is a full,clear, and exact descri tion of the same, reference being had to t eaccompanying drawings, and to the numerals of reference marked thereon,which form a part of this,` specification.

This invention relates more particularly to an improved automaticpapercup forming machine and more particularly to mechanisms for themachine whereby paper cup blanks `are automatically fed singly into themachine and into the field of operation of an adhesive applying padwhich acts at a predetermined-time to apply adhesive to a portion of theblank in a determined conlfiguration, afterwhich the blank is advancedbetween forming dies one of rwhich is spirally grooved so that while theblank is being wrapped around the other die the margin of the adhesivedportion of the blank is not pressed against the main portion of theblank, thereby causing a paper cup to vbe formed wherein none of theadhesive is squeezed out from between overlapping' portions of theformed cup.

l It is an object of the invention to provide an automatic adhesiveapplying mechanism for a paper cup forming machine whereby adhesive isapplied Jto a blank at a predetermined distance from one of the marginsthereof so that when the blank is formed.

into a cup the adhesive will not be pressed out from between theoverlapping portions of the blank.

It is also anobject of the invention to -provide a cup forming machinelwherein the cup blanks while being advanced toward .the forming diesare'acted upon by an adhesive 'applying pad which acts to applv adhesiveto the blanks in apatch of a predetermined shape and at a distance fromone of the margins thereof so that when the blanks are shaped into cupsand stacked they will not stick to one another due to portions of theadhesive being squeezed out from between overlapping portions of theblanks.

It is a further'object of this invention to grooved to prevent pressurefrom being ap -plied to the edge of the adhesivedmargin of a cupblankbemg formed into a cup around the other of said dies. v

Still another object of the invention is to provide a cup formingmachine wherein a blank after bei-ng removed from a magazine is stampedb an adhesive applying' pad and then grippe by a gripping mechamsm and'transferred to a lower level onto a reciprocating table. below resilientretainers to be advanced between forming dies and formed into acupthereby.

It is a further object of the invention/to provide a cup making machinewherein formed glued cups, when discharged from 'forming dies, aredeposited to fall through a curved chute before reaching a cup stackingtube to afford time for the glue to set v before the formed cups arenested one with in the other in a cup holder which is adapted to belowered within the stacking tube each time a formed cup is deliveredthereto.

Another object of the invention is the construction of a cup formingmachine provided with an vadhesive supply rolleragainst'A which arotatable reciprocating adhesive distributing roller is adapted toengage to receive a supply of adhesive and then roll vover areciprocating pad which is adapted to stamp a cup blank with a film ofadhesive before the cup blank is advanced between the cup forming diesof the machine.

It is also an object of this invention to provide a cup making machinewith a cup stacking mechanism having la long chute through which thefinished cups pass before entering a stacking tube in which a cup re vceiver is adapted `to be automatically lowered each time a cup isreceived, said chute being provided with a pivoted shutter adaptedvtoclose the Vlower end of the chute when in closed position to form a stopfor cups in order that a stack of cups may be removed ingfmachineembodying the principles o of the machine.

yfrom ythe stacking tube without necessitating -tion to stampa cup blankwith a film of adhesive in advance of the actionof a transfer mechanismwhich .transfers the adhesivedl blankonto a reciprocating table whichadvances the blank into the field of operation of cup forming dies.

Otheri and further important objects of this invention will be apparentfrom the disclosures in the specification and the accompanying drawings.

The feed reel is rotated by the gear 64 vwhichis in mesh` with the` gear 62` on lthe shaft 61 on which the beve edgear 60 is mounted to be o erated by the beveled gear 59. The bevelegear 59 is'operatedA from the gear 53 which isdirectly'm mesh with thelarge gear 7 operated by the drive gear 6 on the shaft 3. When the feedreel is rotated, the friction pads .68 thereof are brought into contactwith the bottom surface ofthe lowermost cup-blank,and'slidesaidy blankfrom the magazine between the feed rolls 101 andl102.l As the 'blankisjb'eing removed from the 'magazine the trailing A tip thereof isrstpulled out ofengagement inclined guideV pla-te 77.The .,lowrmostblank in the' magazine is l thus delivered tov thez'feed` rollers andthe fstacko'f blanks falls operated by the gear, The cup blank received*between thefrollers 1101 'and-"102 ,is y

fed' forwardly v therebyy v ontovffth'e/ 'station-ary table 33 andbeneath the guide-p "teil3v'5`on which the electric heater 1100;".isfmounted. As the 'cup' blank is dfed onto thestaltionary table one edgeof 'the'cup' blank lslides along `the'-- guidey bar 111 untiltherad-vance Aedgevof the cup blank.I comes into contact with the'stopbar 112.l The cup blank is thus properly centered on they stationarytable with a portion of thejcup blank on which glue is to be applieddisposed over the table opening 34 in the field-of operation of the glueapplying pad 1213. .v

The glue is carried in the tank in which the glue feed roller 123operates. The glue feed roller is rotated from the shaft 61, `the chain129 and thel gear y1,28v whichv rotates the shaft l124v on whichA thefeed roller is mounted. Excess glue carried upwardly by the feed rollerfrom lthe glue box 122 1s scraped from the roller by means of thescraper blade 130./ The' scraper blade.`

130 is adjustable with respectto the feed roller by means of the.tapered screws 134 which coact with4 the beveled block 133 secured onthe scraper blade.

At this stage inthe operation the glue applying pad 113" is in itslowered,y position .(Fig. 16)v and thepad gluing roller'158 is therebyvactuating the arms 154 to cause the blocks 155 to slide forwardly onthe guide rods 156 and thereby advance the'roller 158 which is caused torotate vwhen the Vroller 159 comes in contact with the angle rail 160(Figure 9). The advancin andi'rotating roller 158 isV thus advance,"ofver the.- retracted pad 113 into contactwith the rotating glue feedroller 123. The roller- 158 isv thus supplied with a coating of glue and4the arm 145 is positioned to cause an upward swing of the levers 141thereby elevating the toggle member 140 and causing the same to push thebracket plate 115 upwardly. The glue pad 113 is thus advanced' upwardlythrough Vthe table opening 34 and stamps a film of glue on the undersurface of the cup blank which is heated by the heater 100 so that theglue will readily adhere thereto. The shape of the film' of glue is. ofcourse similar to the shape of the pad 113 as illustrated in Figure 6land is apjied to la particular portion of the cup With lthe applicationof the'film ,of glue to the cup blank, the pad 113 is retracted. Theglue stamped cup blank is'now ready to be transferred from' thestationary table f 33 onto the'reciprocating table 31. When the dies 8and 15 are rotating the table 31.

is reciprocated by means of the -lever 30. The lever 30 is'oscillatedfrom the shaft 26 which is rocked back and forth by the crank armconnected eccentrically by the link 24 to the gear 7 to receive a drivetherefrom. Whenla glue stamped cupblank is on the stationary table 33the table 31 starts to move. back permittin the spring controlled stoparms 191 (lgure 6) to swing upward1` into a vertical position by the"action o the spring 193. The lever now acts to gradually retract thetable-31 bencath the stationary table 33.r Asthe table 31 moves into itsretracted position the crank arm 173 acts on the-connecting..rod

' 174 to swing the bell crank 175-176 from j position upwardl face ofthe cup b ank to clamp a portion of the dot-ted Iline position of Figure10 toward the full line position thereby causing the rack 182 to act onthe gear segment 183 to move the lower gripper jaw 187 into closedagainst the bottom surthe cup blank between the gripper jaws 187 and188.l After the jaws are closed the bel] crank 175-5-176 acts on thecurved arm 186 onto the supporting fingers 39 free from contact with thetable and alittle in advance by causing the presser arm 194 to swing upv wardly away from the table 31to permlt t e cup blank to be movedbeneath the s amel lVith thevad- Vance of the `table 31, the action ofthe camv of the sto-ps 40 and As' the blank lis transferred onto thereciprocating table 31, it is conducted beneath the -tips of theresilient arms 194 and 195 -Which frictionally` contact the uppersurface of the cup blank to pull the cup blank backwardly against thestops 40 and 44 when the table 31 startsto ad- VanceI thereby properlycentering. the cu blank on the table. being transferred onto the table31 the cam .202 (Figure 7) acts on the vroller 201 to When the cup blank1s cause the shaft 198 to partially rotate there- Y onto thereciprocating table.

202 permits the presser arm 194 to be lowered into frictional engagementwith the cup blank. In addition to thespring arms 194 and 195 which actto pull the cup blank into a centered position on the table 31, theupright arms 191 also act to push the cup blank backwardly on theadvancing table andare then' lowered by theadvance end of said tablewhich passes over the same. The centered cup blank is now advanced intothe field of operation of the dies 8 and 15 to be gripped thereby as thetable 31 again starts to move back. As the advancevend of the cup blankis projected between the separated dies 8 an. 15 the raised portion ofthe cam.10rotates away from the roller 11 thereby permitting the sleeve12 to be lowered so that the presser die 15 moves downwardly toward theforming die 8 clamping the advance portion of the cup blank between thedies. The cup blank is thus automatically fed into the'fi'eld ofoperation of the forming dies.

The cup forming die 8, the main portion of the blank firstbeing formedinto a cup' around the die 8 after which the glued portion .of the blankis graduallyl wrapped around the body of the cup to reinforce the same.As the glued port-ion of the cup blank is Wrapped around the conicalcup, the spiral groove 16 of the presser die 15 engages over the margin17 Figures -18 and 1,9) of the cup blank thereby preventing anyvpressure from being applied'to said margin 17. The glue is accordlnglynot pressed out from below the margin 17 and sticking of the formedcups, one within the other, is thus obVated. The

.completed cup is thus/,formed on gthe die 8 ready to be automaticallydischarged from the forming. die by'a blast of air from .the air, pipe 203 similar to the arrangement disclosed in my co-pending application forPatent Serial Number 259,986 for anAutolnatic cup forming machine filedOctober When a cupis inished the presser die 15 is of course firstseparated from the forming blank is now formed around the llll die bytheaction of the beveled cam on the roller 11. The cup being released bythe resser die itis discharged fro-m the formlng die and falls into thecurved chute 5,204 and then enters the top of the receiving tube 205 tobe received by the cupI holder provided within the tube and supportedonthe end of the movable arm 206. The curved chute 204is provided toafford a long path between the forming die 8 and the cup stacki ing tube205 so that therewill be a short i lapse oftime sufficient to permit theglue to 205 the movable supporting arm 206 is lowset before the cupenters the stacking tube 205 and is pressed against other cups withinthe tube.y

Each time a cup is delivered into the tube ered a predetermined distanceby the action f of the bar 218 which operates the pawl217 and theratchet wheel 216. VVhenfthe tube v is filled by a stack of nested cupsthe shutter A207 is moved into closed position across the bottom of thechute 204 to receive cups while the stack of cups in the tube 205 isremoved.

' It will thus be noted that the machine need not be stopped during thetime the tube 205 visemptie pull the latch bolt 94 from the full lineposition ofy Figure 13 into the d'otted'line release position of saidfigure. The plate is thus readily released and may be swung upwardly bymeans of the handle 88 about the shaft 87 ,(Figure 15) until the pin 86strikes against the bar 82. When the plate 35 is yswung upwardly the camblock 84 acts against the pin 83 thereby pulling the bar 82 forwardly.Forward movement of the bar 82 acts to swing-the crank armq81 upwardlyto partially rotate the shaft 78 where by the lifterarms 7 9 (Figure 1)are swung upwardly to raise the stack of cup blanks in the blank holdingmagazinefout of the field of operation of the blank feed reel pads 68.80 thatno c'up blanks willfbe delivered from 'the magazine to thevblankfeed rollers 101 and 102 when the plate 35 is raisedand the machinecontinues operating. l

\Forward movement of lthe bar 82 also' causes the crank arm 170 on thesleeve 80 vto swing downwardly from the position illustrated in 'Figure2 to lower the rod 171 and push the flattened lower end thereof infro-nt of the stop screw 163. The lower end of the rod 171 is thuspositionedto be contacted by the boss 162 on thecrank arm 161F therebyshortening the forward throw of the levers 153 on the shaft 142 so thatthe arms 154 will not move the glue applying roller l 158 forward farenough to come into contact' with the glue feeding'roller 123. Nogluefrom the roller 123J is distributed to the glue applying roller 158when the' plate 35 is ralsed.

It will be noted that rwhen 1t becomes necessary to raise the blankguide pla-te 35 that the cam block 84 automatically acts to causeelevation of the cup blanks inthe magazine so that the feed of cupblanks into the machine is discontinued aswell asthefeeding of gluetothe roller 158 and fromsaid roller to the glue stamping pad 113.,

I am aware that numerous details ofconv struction may be varied througha wide .range without departing fromthe principles of this invention,and I therefore do not pur pose limiting the patent granted otherwiseone of said dies having a spiralgroove'therein to engage over the marginof the ad-l hesived portion of the cup blankl so thatno pressure will beapplied to saidmargin during the forming of the cup.
